  • Active key rolling for sensitive data protection
    Patent number: 10860724
    Abstract: In aspects of active key rolling for sensitive data protection, a data security system includes memory storage implemented as a data store to maintain a batch of sensitive data instruments each encrypted with a previous encryption key. A data encryption service can receive a request from a client device for data in a sensitive data instrument from the batch of the sensitive data instruments. The data encryption service can decrypt the sensitive data instrument with the previous encryption key making the requested data in the sensitive data instrument available for access by the client device. The data encryption service can then re-encrypt the sensitive data instrument with a new encryption key effective to update the encryption of the sensitive data instrument, the updated encryption being triggered based on the request for the data and the decryption of the sensitive data instrument.
